hello all! we're having a dairy seder again this year, and one of the sort of main dishes i was thinking of making was a cauliflower gratin (cauliflower, heavy cream, cheese - basics), and i was hoping for some suggestions on any special extras that i could add in to make it a little more exciting. no meat, no bread-type items, no corn - other than that, i'm open to any recommendations! thanks for the help!
